  • Patient-operated pacemaker programmer
    Patent number: 4365633
    Abstract: There is disclosed a pacemaker programmer for operation by a patient. The programmer can be pre-set by the physician to allow the patient to set his pacemaker in any one of a limited number of states, the states controllable by the patient being a sub-set of the set controllable by the physician with use of his conventional-type programmer. In the illustrative embodiment of the invention, while the physician programmer can control eight different rates, the patient programmer can set only three of these ("exercise", "awake" and "sleep" values), the particular values being preselected by the physician.
